Abstract
A growing body of evidence shows that air pollution information can induce protective behaviors, yet few studies have focused on high-exposure populations in developing economies, particularly those affected on the roads. This study provides experimental evidence on the impact of granular air pollution information on the behavior of motorcycle taxi drivers in Nairobi, Kenya, an occupation with high on-the-job exposure. We conduct a randomized controlled trial (RCT) with Boda motorcycle drivers in Nairobi. Participants are randomized into four groups: a control group; a treatment group receiving information on the potential harms of pollution (Awareness); a second treatment group receiving access to an interactive, street-level air pollution map (Street-Level Map); and a final treatment group receiving both interventions (Awareness + Street-Level Map). For this study, we produced high-frequency, street-level air pollution data by equipping a small sample of both electric (EV) and non-EV Boda taxi drivers with mobile pollution monitors from July 2025 to January 2026 (Marty et al., 2026). The primary outcomes of interest are the drivers' pollution aversion behaviors. We will also calculate the perceived value drivers place on avoiding pollution by analyzing trip pricing information.
